1、 ENGINEERING MATERIAL SPECIFICATION Date Action Revisions Rev. 00 2017 01 18 Released R. Harris, NA Controlled document at www.MATS Copyright 2017, Ford Global Technologies, LLC Page 1 of 9 POLYAMIDE (PA) 6, 15% GLASS FIBER REINFORCED WSS-M4D665-B2 MOLDED IN COLOR, INTERIOR 1. SCOPE The materials de
2、fined by these specifications are 15% glass fiber reinforced, polyamide 6 molding compounds for general purpose and interior use. 2. APPLICATION This specification was released originally for material used for functional parts. 2.1 LIMITATIONS These materials absorb and retain moisture. Part design
3、and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material is not suitable for long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for use a
4、bove 155 C. These materials are not intended for painted applications. Materials approved to these specifications do not require testing to WSS-M99P2222-D1/Latest Performance, Vehicle Interior Environment Quality Material/Component Requirements. If collective parts exceed 100 cm2 or 100 g testing wi
5、ll be required per the appropriate performance specification 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or oth
6、er documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS Dry as molded All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except whe
7、re noted (Moisture Conditioned) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2%,conditioning the material for a minimum o
8、f 16 h at 40 to 50 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. ENGINEERING MATERIAL SPECIFICATION WSS-M4D665-B2 Copyri
9、ght 2017, Ford Global Technologies, LLC Page 2 of 9 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. The material supplier shall en
10、sure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.4 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011, identified certai
11、n requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.4.2 This specification i
12、s based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.4.3 The use of regrind is permitted, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the allowable amount of regrind and the maximum allo
13、wable regrind content must be specified on the engineering drawing. Any changes to what is specified on the drawing (no specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA). 3.4.4 Performance Criteria: Parts using
14、 these specifications must comply with all the requirements of WSS-M15P4-G/Latest (MIC interior) and fulfill applicable SDS/CDS requirements. 3.4.5 As specified in WSS-M99P1111-A, paragraph 3.2, Ford Materials Engineering may request a Control Plan and Certificate of Analysis (CoA) containing lot te
15、sting requirements which must include, but are not limited to: Filler Content Impact Strength, Notched Charpy at 23 C Tensile Modulus 3.5 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-end gated test specimens. The test specimens A and D shall b
16、e molded using molding conditions defined in ISO 1874-2. See Tables 1 and 2 for the number of samples required. Specimens shall be as follows: Specimen A 150 minimum x 10 x 4.0 +/- 0.2 mm (ISO 527-2, Specimen Type 1A) Specimen B 355 x 100 x 1.0 +/- 0.1 mm (ISO 3795) Specimen C 145 x 60 x 3.2 +/- 0.2
